GAS-B'URNER.

SPECIFICATION forming part of Letters Patent No. 622,187, dated March28, 1899.

Application filed March 5, 1898. Serial No. 672,737. (No model.) 7

To all whom it may concern.-

Be it known that I, WILHELM FRIEBERTS- HAUSER, a citizen of the UnitedStates of America, residing at Pittsburg, in the county of Allegheny andState of Pennsylvania, haveinvented certain new and useful Improvementsin Gas-Burners, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to certain new and useful improvements ingas-burners; and it has for its object to reduce the quantity of gasconsumed and at the same time retain or increase the heating capacity ofthe burner.

Other novel objects of my invention are to provide a burner in which thegas is brought into direct contact therewith and is heated in such amanner as to expand before it reaches the point of combustion. Y

My improved burner also aims to provide novel and effective means forthe commingling of the gas and air previous to the gas reaching thepoint of ignition, and thereby obtain a perfect combustion. To assist inthis, I aim to so construct the mixer that the air will become heatedbefore it is mixed with the gas.

The novel features of construction whereby the above results areobtained will be specifically referred to by reference to theaccompanying drawings, in which- Figure 1 is a top plan view of myimproved burner. Fig. 2 is a vertical sectional view of the same. Fig. 3is an underneath plan view. Fig. 4c is a perspective view.

To put my invention into practice, I provide a circular drum or casinga, which may be of any suitable size and has formed inte gral therewithand centrally arranged an inner drum b, which extends upwardly to thetop of the circular drum or outer casing a. This inner drum is providedwith apertures 0, arranged around its periphery, which permit the airand gas to escape from the inner into the outer drum. The bottom of thisinner drum is closed by means of the plate 61, provided withperforations d to admit the air into the said inner drum, said plate clbeing provided with a central aperture to rethe inner drum and connectedto the supplypipe f by a union g or other suitable means. Thissupply-pipe f is provided with small openings h, through which the gasescapes into the inner drum.

Arranged in the top of the burner and fitting neatly within the outerdrum is a plate 70, which is provided with notches or serrations kentirely around its periphery, which permit the gas to escape throughthe outer drum to the top of the burner, where it is ignited. This plateis held in its position by means of the nut or screw-cap Z, whichengages the top of the gas-pipe e, and thereby holds the burner in itsposition.

Through this construction of a burner it will be observed that when thegas is ignited the heat of the same will cause the gas and air passinginto the outer drum to become heated previous to reaching the point ofignition, thereby materially aiding perfect combustion. It will beobserved also that such a construction of the burner may be readilyapplied to any stove or furnace without requiring any special fitting,and the simplicity of construction will enable any one to readily applythe same.

Having fully described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. In a gas-burner, an outer drum, an inner drum arranged centrallytherein, said inner drum being provided with openings in its walls, atop plate or cover for the outer drum, said plate or cover beingprovided with notches or serrations entirely around its periphery whichform outlets for the gas, a gassupply pipe arranged centrally of saidinner drum and passing through the plate or cover of the outer drum toreceive fastening means to hold said plate or cover in position, saidsupply-pipe being provided with openings opposite to the openings in thewalls of the inner drum for the escape of gas into the same,substantially as shown and described.

2. A gas-burner comprising in combination, an outer drum and acentrally-arranged inner drum provided with perforations communicatingwith the outer drum, a gas-supply pipe arranged centrally of the innerdrum and provicled with openings through which the gas or cover is heldin position, substantially as escapes, a top plate or cover for theouter shown and described. 10 drum, said plate or cover being providedwith In testimony whereof I affix my signature notches or serrationsentirely around its pein the presence of two witnesses.

riphery and provided also with a central \YILIIELM I RIEBER'ISIIAUSER.aperture'tln'ough which the gas-supply pipe Vitnesses: passes, and a nutor screw-cap engaging the JOHN NOLAND,

end of said gas-supply pipe whereby the plate I H. II. PATTERSON.
